Diaphragm Gas Meters

The CHEKKER is a patented meter which generates a two-digit check number in its index. The number is generated mechanically and the system requires no maintenance. This check number is encoded. When the meter is read out the check number is also registered and, with the help of a software module, the number enables the user check whether the meter reading is right or wrong. To do this, the check number is automatically decoded before the data is processed by the billing system.
